On June 28, 1969, fed up after a police raid, a group rioted outside a popular New York City gay bar, the Stonewall Inn. The clash came to be known as the “Stonewall Riots” and marked the birth of the gay rights movement. Just two days before Stonewall’s forty-forth anniversary, the Supreme Court struck down the seventeen-year-old Defense Of Marriage Act (DOMA) as “unconstitutional as a deprivation of the equal liberty of persons that is protected by the Fifth Amendment.” The court also dismissed California’s Proposition 8 appeal, potentially giving millions of California gay and lesbian residents the right to marry.

“By denying recognition to same-sex couples who are legally married, federal law discriminates against them to express disapproval of state-sanctioned same-sex marriage. This decision means that same-sex couples who are legally married must now be treated the same under federal law as married opposite-sex couples.”

So, gay and lesbian couples in states with existing marriage equality laws have been affirmed. But what about the other 37 states? What will happen to them? The court did not ensure marriage equality for the states still left without same-sex marriage laws, but the political implications of the decision are sure to reverberate, pressuring remaining states to follow suit.

Barney Frank, Washington D.C. Rep. Barbara Lee, and Professor of Constitutional Law at New York University, Kenji Yoshino.
